Creating JavaFX sequences from Java code

Saturday, March 21st, 2009 - 8:15 pm - JavaFX

Scroll down for the full source.  Today, to execute code asynchronously in JavaFX, the background code must be written in Java.  Ideally, your Java code will return JavaFX data types, keeping your FX code clean and helping you be prepared for the day when you won’t need Java.

This is how you can create and return JavaFX sequences from your Java code.

Set the return type of your method to com.sun.javafx.runtime.sequence.Sequence.  Many of the com.sun.javafx classes seem to have been created for use in Java code.

@Override
public Sequence<String> call() throws Exception {

In your code, use any type of collection class you like.  It’s easiest to use List classes, though, because they can be directly converted.

List<String> names = Arrays.asList("Arthur", "Trillian", "Zaphod");

Then, convert the list to a sequence using com.sun.javafx.runtime.sequence.Sequences and return it.

return Sequences.make(TypeInfo.getTypeInfo(String.class), names);

Here it is all together for impatient people like me.

@Override
public Sequence<String> call() {
  List names = Arrays.asList("Arthur", "Trillian", "Zaphod");
  return Sequences.make(TypeInfo.getTypeInfo(String.class), names);
}
